Thomas came into the day with a two-stroke lead thanks to incredible consistency over the first three days, posting a 67 in three consecutive rounds.

He continued his impressive performance with some big-time drives on the open course. PGA Tour showed one long drive that almost reached the green:

He earned a birdie on the hole, while Matsuyama struggled to a bogey, turning a one-stroke lead into a three-stroke cushion going into the final hole.

Matsuyama earned a birdie on No. 18, but it wasn't enough to catch Thomas, who birdied on his final two holes to secure the win.

Thomas showcased incredible consistency throughout the week, earning scores of 67 on the first three rounds. His final round was a 69, which was more than enough to come away with his second victory of the year.

While many of the big names are just getting their season started, Thomas and Matsuyama have taken the early advantage in the FedEx Cup standings.

Jordan Spieth had a bit of a rough week early with a few big numbers on the scorecard in the first two rounds. However, he was outstanding Sunday as a legitimate threat to catch the leader despite starting the day 10 strokes back.

His 65 in Round 4 tied the lowest score of anyone in the tournament, featuring eight birdies and zero bogeys.

Golf Channel broke down the American's week:

27 eagles/birdies = 😀
3 others = ☹

He followed this up with a birdie on the next hole, but a second double bogey right after effectively ended any chance he had of climbing back up the leaderboard. He finished four strokes over par on the back nine, dropping him into a tie for ninth place.

This was a tournament with only 32 entries and no cuts, but it was a loaded field that featured Dustin Johnson, Jason Day, Patrick Reed, Bubba Watson and others. Johnson had three rounds of 69 on the week to earn a tie for sixth, while Day ended his tournament well with a birdie on his 72nd hole to finish with a 13-under in a tie for 12th.

In the end, though, it was Thomas who came away with a solid victory to continue his strong 2017 season.

Many of these competitors will now stick around for the Sony Open in Hawaii, which will take place next week at Waialae Country Club in Honolulu.

Post-Tournament Reaction

Thomas earned his second win of the 2017 season, and he believes this isn't a fluke.

"I felt confident coming in," Thomas told Golf Channel after the win, per Kyle Porter of CBSSports.com. "I proved a lot. It's a great start to the 2017 year and hopefully just a sign of more things to come. "

Meanwhile, Spieth had high praise about his good friend Thomas.

"I think it's potentially floodgates opening," Spieth said, per the Associated Press (via PGATour.com). "The guy hits it forever. He's got a really, really nifty short game. He manages the course well. He's playing the golf course the way it should be played, and honestly, he's taking advantage of the easier holes. It's awesome to see."

It's still early, but both Thomas and Spieth could be headed toward big years based on their performances this week.
